The present invention concerns a spotlight adapted for a light device, said spotlight comprising a support and at least one light module adapted for producing a light beam and comprising at least one light source, such as a light emitting diode (LED) and an optical element, such as a lens, wherein the light source and optical element are adapted for being positioned in extension of each other in an optical axis.

FIELD OF INVENTION

The present invention concerns a spotlight adapted for a light devicesaid spotlight comprising a support and at least one light moduleadapted for producing a light beam and comprising at least one lightsource, such as a light-emitting diode (LED) and an optical element,such as a lens.

STATE OF THE ART

Spotlights adapted for a light device are already known in the state ofthe art. As a general rule, a light device comprises a base and aspotlight forming an element articulated or pivoting in relation to saidbase. The base is used, for example, to fix the light devices on abearing surface such as a wall, a ceiling or also a structure, suitablefor enabling said light devices to be visible, but also to light a spacearound said light devices. The spotlight comprises multiple lightsources capable of emitting light beams.

If the light device is installed using the base, the spotlight can pivotin relation to this base in order to adjust the position of saidspotlight in relation to said base and thereby determine the directionin which the light beams are emitted.

In the field of show business, and more particularly plays and musicalshows, use of light devices represents a substantial part of the décor,thereby making it possible to generate particular light effects. Lightdevices are used to supplement the visual image offered to thespectators. During normal use of these light devices, it is possible tomaterialise the light beams thanks to a “mist” type smoke. This mistforms the medium on which the various light beams are rendered visibleto the spectators.

In the field of show business, there is a constant need to improveexisting systems and provide users with greater freedom to manipulatethe spotlights in order to create innovative special effects.

The object of the present invention consists in proposing a spotlightadapted for a light device, said spotlight comprising a support and atleast one light module adapted for producing a light beam and comprisingat least one light source, such as a light-emitting diode (LED) and anoptical element, such as a lens, wherein the light source and opticalelement are adapted for being positioned in extension of each other inan optical axis, wherein the spotlight comprises adjustment means foradjusting the relative position of the light source and of the opticalelement so as to modify the shape of the light beam.

A first advantage of this characteristic lies in the fact that thespotlight comprises, on its front face, i.e. on the face comprising theoptical element and the light source adapted for producing a light beam,an optical element which is essentially square-shaped, preferablysquare-shaped. The spotlight support comprising at least one lightmodule may be adapted so that the assembly composed of the support andof the light module is essentially square-shaped, preferablysquare-shaped. In other words, if the spotlight is used in combinationwith other spotlights of the same type, the multiple spotlights arecapable of forming together a surface comprising said multiplespotlights which is essentially rectangular shaped.

Each spotlight can comprise multiple light modules, each light modulehaving an optical element essentially presenting a square shape,preferably a square shape. In other words, each spotlight can present afront face adapted for diffusing light beams and which are essentiallyrectangular shaped, preferably rectangular shaped.

According to the invention, the various light modules in a spotlight canbe positioned in the spotlight in order to form a grid. Use of opticalelements which are essentially square-shaped, preferably square-shaped,makes it possible to obtain a spotlight comprising a front face on whichthe various optical elements are positioned in proximity to each otherwith minimal loss of space between them. The assembly composed of saidoptical elements offers a rectangular optical surface. The minimal spacebetween the various adjacent optical elements enables the spotlight topresent an optical surface which is in the shape of a rectangularscreen.

The option of positioning such rectangular optical elements in proximityto each other presents a major difference with regard to the lightdevice disclosed in the prior art.

Indeed, the light device according to the state of the art comprisesadjacent optical elements each presenting an essentially circular shape,which causes the presence of a relatively large unused surface areabetween said adjacent optical elements.

More particularly, the adjustment means are adapted for adjusting thedistance between the light source and the optical element in thedirection of said optical axis.

More particularly, the adjustment means are adapted for adjusting therelative position of the light source and of the optical elementperpendicularly to that of said optical axis.

More particularly, the spotlight comprises a first part comprising saidat least one optical element and a second part comprising said at leastone light source, said adjustment means being adapted for adjusting thedistance between the first part and the second part of the spotlight.

More particularly, the first part is adapted for, at least partially,enclosing the second part and enabling said second part to move insidethe first part.

More particularly, the first part forms the exterior wall of thespotlight.

More particularly, the first part comprises, on its exterior, connectionmeans for connecting the spotlight to a bracket.

More particularly, the spotlight comprises multiple light modules, saidlight modules being positioned beside each other to form together a gridcomprising at least one row and one column, preferably to form arectangle.

More particularly, the light elements are positioned in a grid shapecomprising the same number of rows and the same number of columns.

More particularly, the optical element is essentially square-shaped,preferably square-shaped.

More particularly, the spotlight is connected to the bracket in a secondrotation axis.

More particularly, the second rotation axis is adapted to enableunlimited rotation of the spotlight in relation to the bracket.

FIG. 1 represents a light device 50 according to a first embodiment ofthe invention. The light device 50 comprises a spotlight 1 fixed on abracket 2 with connection means so that said spotlight 1 can pivot inrelation to said bracket 2 around a rotation axis 51. According to theinvention, the spotlight 1 is adapted for pivoting, in an unlimitedmanner, around the rotation axis 51, from 0° to 360° and beyond. Inother words, the connection means between the spotlight 1 and thebracket 2 are adapted to enable transfer of electrical energy andelectrical signals from said bracket 2 toward the spotlight 1 thanks toa rotary contact. The rotation of the spotlight 1 in relation to thebracket 2 takes place without the rotary contact limiting the rotationof said spotlight 1 in relation to said bracket 2.

The bracket 2 is connected to a base 3 with connection means. Theconnection of the bracket 2 on the base 3 is adapted and enablesrotation of said bracket 2 in relation to said base 3 around a rotationaxis 52. According to the invention, the bracket 2 can pivot in anunlimited manner in relation to the base 3 around the rotation axis 52from 0° to 360° and beyond. The connection means between the bracket 2and the base 3 are adapted to enable transfer of electrical energy andelectrical signals from the base 3 toward the bracket 2 thanks to arotary contact. Hence the rotary contact does not limit rotation of thebracket 2 in relation to the base 3.

The base 3 of the light device 50 is adapted for fixing said lightdevice 50 on a bearing surface, such as a wall, a ceiling or any othersuitable support structure.

During normal use of the light device 50 according to FIG. 1, thespotlight 1 is adapted for pivoting in relation to the base 3 around thefirst rotation axis 51 and around the second rotation axis 52. Thecombination of these rotations makes it possible to obtain lighteffects.

The spotlight, 1 according to the first embodiment represented in FIG.1, is present essentially in a panel shape. The shape of said spotlight1 is shown in FIGS. 1, 2, 3 and 4. The spotlight 1 comprises a setquantity of light modules. The various components as well as the use ofsuch light modules are described in detail in FIGS. 9 to 18. Said lightmodules are equipped with at least one light source, such as alight-emitting diode (LED), and a least one optical element 4 such as alens. The lenses 4 of the light device of the spotlight 1 are visible inFIG. 1 and represented essentially in a square shape, preferably in asquare shape. The detailed representation of a lens 4 is visible inFIGS. 8a and 8 b.

According to the embodiment represented in FIG. 1, the spotlight 1comprises 25 light modules comprising lenses 4. As the lenses 4 areessentially square-shaped, the light modules of the spotlight 1 formtogether an optical surface covering practically the whole of the frontface of said spotlight 1. Thus, the space between the various lenses 4is relatively restricted. The lenses 4 of the light modules of thespotlight 1 can form an optical surface presenting a screen shape inorder to create special light effects. The light effects which can thusbe obtained thanks to the shape of the lenses 4 are detailed in FIGS. 9to 11.

FIG. 2 represents a side view of the light device 50 according to FIG. 1in which it is possible to distinguish the thickness of the spotlight 1,said thickness making it possible to contain the various light modules.Each light module comprises at least one light source (not shown in FIG.2) producing a set quantity of heat. The interior of the spotlight 1houses a cooling system (not shown) intended for cooling the variouslight sources. The spotlight 1 is equipped with a grille 11 making itpossible to generate an air flow between the interior and exterior ofthe spotlight 1. Said air flow thus makes it possible to cool theelements situated inside said spotlight 1 but also to exchange heat withthe environment in which the light device 50 is used.

FIG. 2 shows the relatively convex shape of the lenses 4. The convexshape of the lenses 4, associated with the light sources present withinthe spotlight 1, makes it possible to create light beams.

FIG. 3 represents a perspective view of the light device 50 according toFIGS. 1 and 2. FIG. 3 shows the front face of the spotlight 1 comprisinga support structure 12, making it possible to hold the various lenses 4in relation to each other in a set position.

FIG. 4 shows the rear face of the light device 50 according to FIGS. 1,2 and 3. Furthermore, FIG. 4 represents the rear part of the base 3comprising a multitude of connection means for connecting said base 3 toan electrical energy source and to a control system. The control systemmakes it possible to transmit control commands for a set use of saidlight device 50 according to the invention. The electrical energy andelectrical control signals sent to the base 3 are transmitted via thebracket 2 in the direction of the various light modules present insidethe spotlight 1.

FIG. 5 represents an assembly of light devices 50 as described in FIGS.1 to 4, wherein the various spotlights 1 of said light devices 50 formtogether a surface on which images can be represented. It should benoted that, according to the invention, the various light modules ofeach light device 50 are adapted for receiving instructions intended forusing the light sources of said light modules. Indeed, the intensity andcolour of the light beam to be generated can be controlled for each ofsaid light modules. Combined use of the light modules of the variousadjacent spotlights 1 makes it possible to represent an image over thewhole of the surface formed by spotlights 1 of the light devices 50. Theuse of said light devices 50 is represented in FIG. 6.

According to FIG. 6, the various spotlights 1 of the light devices 50are positioned together so as to form a grid measuring 5×5 light devices50. It is possible to use any other quantity of light devices 50 to forma grid thus composed of a number of horizontal rows and verticalcolumns.

As stated above, the various spotlights 1 represented in FIG. 6 arerotationally mobile in the rotation axis 52. The image thus obtainedwith the aid of said spotlights 1 can therefore be modified. The imagecan be modified by selective use of one or more light modules within thevarious spotlights 1 of the adjacent light devices 50. Alternatively,the image can be modified by pivoting said various spotlights 1 of saidlight devices 50 in relation to each other in the rotation axis 52,thanks to the rotary contact enabling rotation in relation to therotation axis 52 between the bracket 2 and the base 3. The result of therotation of the spotlights 1 in relation to each other is represented inFIG. 7. Additionally, each spotlight 1 can also pivot around the axis 51in relation to said bracket 2 to which said spotlight 1 is connected.The combination of individual use of the various light modules in thevarious spotlights 1 of the light devices 50 and the possibility ofpivoting the various spotlights 1 around the rotation axes 51, 52 offersthe user great freedom in terms of obtaining light effects.

FIGS. 8a and 8b show an embodiment of lenses 4 which have an essentiallysquare shape. FIG. 8a represents a perspective view of the lens 4. Thelens 4 presents an essentially flat base surface 41 also shown in FIG.8b . The opposite surface 42 to the base surface 41 presents a convexshape. The lens 4 comprises four sides 43 essentially perpendicular tothe base surface 41 of said lens 4. According to a particularembodiment, the lens 4 is composed of plastic and is obtained, in thisspecific case, thanks to a moulding process. In order to enable optimalintroduction of a set quantity of plastic into a mould, the lens 4 isequipped with an injection point 44 indicated in FIG. 8 a.

FIG. 8b represents the base surface 41 of the lens 4 comprising a centre0. During conventional use, the base surface 41 is positioned on thelight source side. A detailed representation of use of the assemblycomposed of a lens 4 and a light source is shown in FIGS. 9, 10 and 11.

FIGS. 9a, 9b, 10a, 10b, 11a and 11b show three different modes of use ofa light module 60 according to the invention. The light module 60, asrepresented in FIG. 9a comprises a printed circuit 7 such as a thermalsubstrate (MCPCB) on which a light source 8 is positioned, such as alight-emitting diode (LED). A light guide 9 comprising an end 92 ispositioned above said light source 8, said light guide 9 having thefunction of guiding the light, produced by the light source 8, in thedirection of the lens 4. As a general rule, said light guide 9 comprisestwo components. The first component forms the exterior of the lightguide 9, as shown in FIG. 9, and makes it possible to give sufficientrigidity to said light guide 9. The second optical component (notshown), generally made using plastic, can be found inside the lightguide 9. The second component presents an optical characteristic makingit possible to direct the light from the light source 8 toward the lens4 and comprises an optical axis 61. The first component of the lightguide 9 comprises lugs 91 intended to position and fix said light guide9 on the printed circuit 7.

The light source 8, the light guide 9 and the lens 4 are positionedaround the optical axis 61 such that the centre of the light source 8,the optical axis 61 of the light guide 9 and the centre 0 of the lens 4are in extension of each other. As shown in FIG. 9, the base surface 41is situated at a distance “I” from the upper end 92 of the light guide9. The distance “I” between the light guide 9 and the lens 4 has aninfluence on the exit angle of the light beam produced by the lightmodule 60. As a general rule, it proves that the shorter the distance“I” between the light guide 9 and the lens 4, the greater the exit angleof the light beam obtained by the light module.

In the example shown in FIG. 90, the distance “I” between the upper end92 and the base surface 41 of the lens 4 is between approximately 2 and5 mm inclusive. Using a distance in this order of magnitude makes itpossible to generate a light beam presenting an exit angle greater than40° in relation to the optical axis 61. Such an angular amplitude offersa configuration in which the spotlight 1 is generally intended todisplay colours and images.

According to the configuration represented in FIG. 9a , the lightobtained using the light module 60 has rather a decorative function. Inthe technical field, the type of light used with the mode of use asshown in FIG. 9a is referred to using the term “washlight”.

In FIG. 9b , a circle 62 represents, schematically, a cross-sectionalview of the shape of the light beam 20 obtained with the aid of thelight module 60 according to the configuration shown in FIG. 9a . Acircular shaped light beam 20 is obtained thanks to the distance “I” andto the shape of the lens 4, said light beam comprising, as indicatedabove, an exit angle greater than 40° in relation to the optical axis61.

FIG. 10a shows a light module 60, represented according to a second modeof use. According to FIG. 10a , the distance “I” between the upper end92 of the light guide 9 and the base surface 41 of the lens 4 is betweenapproximately 5 and 25 mm inclusive. Hence, the distance “I” betweensaid upper end 92 and said base surface 41 according to the mode of userepresented in FIG. 10a is greater than that of the mode of userepresented in FIG. 9a . Thus the light beam obtained comprises an exitangle less than the exit angle obtained according to the mode of userepresented in FIG. 9 a.

In FIG. 10b , a square 63 represents, schematically, a cross-sectionalview of the shape of the light beam 20 obtained according to the mode ofuse in FIG. 10a . In this embodiment, the essentially square shape ofthe lens 4 has an impact on the shape of the light beam. Indeed, thelight beam obtained also presents an essentially square shape and anexit angle between 10° and 40° inclusive in relation to the optical axis61, as a function of the distance “I” between the light guide 9 and saidlens 4.

FIG. 11a represents a third mode of use of the light module 60.According to FIG. 11a , the distance “I” between the upper end 92 of thelight guide 90 and the base surface 41 of the lens 4 is betweenapproximately 25 and 40 mm inclusive. Thus, the distance “I” accordingto the third mode of use is greater than that of the mode of use shownin FIG. 10a . The objective of using a relatively large distance “I”between the light guide 9 and the lens 4 consists in obtaining a lightbeam 20 having a relatively restricted exit angle in relation to theoptical axis 61. The light module 60, according to the mode of userepresented in FIG. 11a , can produce, within the environment in whichthe spotlight 1 is situated, light beams used as “light sticks” whichcan move over a relatively long distance.

In FIG. 11b , a circle 64 represents, schematically, a cross-sectionalview of the shape of the light beam 20 obtained according to the mode ofuse in FIG. 11a . In the example according to FIG. 11b , a light beamhaving an exit angle of between 3.5° and 10° inclusive can be obtained.

The light beams 20 from the light device 50, obtained according to themodes of use represented in FIGS. 11a and 11b , are clearly visible inthe environment where said light device 50 is used, thanks to a “mist”type smoke. Said light beams 20 are rendered visible in a similar way to“light sticks” and give the impression of forming “light bodies” presentin three dimensions in space. The presence of the “light sticks”combined with the possibility of pivoting the spotlight 1 thanks to therotation axes 51, 52, enables the user to obtain spectacular lighteffects.

FIG. 12 represents a schematic view of the interior of the spotlight 1for a light device 50 as represented in FIGS. 1 to 7. The spotlight 1according to FIG. 12 comprises means described below and enabling thelight module of said spotlight 1 to operate according to the operatingmodes represented in FIGS. 9a, 10a and 11 a.

As shown in FIG. 12, the spotlight 1 comprises an exterior wall 14 and asupport element 12, present on the front face of said spotlight 1, saidsupport element 12 being intended to hold multiple lenses 4. There arefive lenses 4 represented in FIG. 12. A printed circuit 7, presentinside the spotlight 1, comprises light guides 9. Five light guides 9are visible in FIG. 12, each of them positioned so as to cooperate,respectively, with a lens 4. Twenty-five light guides 9 are installed onthe printed circuit 7, inside the spotlight 1, and cooperate with anequal quantity of lenses 4 present on the front face of the spotlight 1.The assembly of light guides 9, positioned on the printed circuit 7, isvisible in FIG. 17.

It should be noted that, for reasons of clarity and comprehension,several elements of the interior of the spotlight 1 are not representedin FIG. 12. By way of example, the spotlight 1 comprises a coolingsystem (not represented) making it possible to dissipate the heatproduced by the various light sources.

With the aid of adapted adjustment means, the assembly comprising theprinted circuit 7 and the light guides 9 can be moved in order toposition said light guides 9 at an adapted distance from the lenses 4and to enable operation of the light modules 60, as described in FIGS.9a, 10a and 11a . In FIG. 12, the optical axis 61 is indicated for oneof the light modules. As shown in FIGS. 12 and 13, the spotlight 1 isequipped, in its interior, with adjustment means comprising a first rail15 and a second rail 16, both positioned so that the assembly composedof the printed circuit 7 and of the light guides 9 can move, on the onehand toward the lenses 4 and, on the other hand, in the oppositedirection, as shown with the aid of the arrow 17 in FIG. 12. It shouldbe noted that the first and second rails 15, 16 are positioned such thatthey enable movement of the assembly composed of the printed circuit 7and the light guides 9 parallel to that of the optical axes 61 of thevarious light modules 60 inside the spotlight 1.

As shown in FIG. 13, the adjustment means also comprise movementmechanisms each comprising a motor 18 and a belt 19. Depending on thedesired use of the spotlight 1 according to one of the modes representedin FIGS. 9a, 10a and 11a , a control signal is sent to the motors 18 inorder to move the belts 19 and, thus, move the assembly composed of theprinted circuit 7 and of the light guides 9 toward a chosen position, bymeans of the first and second rails 15, 16.

It should be noted that the assembly of the first and second rails 15,16, the motors 18 and the belts 19 is all positioned inside thespotlight 1. Thus, the movement of the assembly composed of the printedcircuit 7 and of the light guides 9, in relation to the lenses 4, is notvisible outside of the spotlight 1. The technical effect of the abovelies in the fact that the user can use the light module 60 byalternating between the embodiments according to FIGS. 9a, 10a and 11awithout modifying the exterior appearance of the spotlight 1. Thus, forthe spectator, the change in mode of use of the light module 60 takesplace imperceptibly insofar as the spotlight 1 does not undergo anyexternal modification.

FIG. 14 shows a second embodiment of a light device 150 comprising aspotlight 100, fixed to a bracket 102, according to which said spotlight100 presents a first exterior part 114 and a second exterior part 115.Lenses 104 are fixed on the first exterior part 114 and the assemblycomposed of a printed circuit 107 and light guides 109 is fixed on thesecond exterior part 115, on the exterior of the spotlight 100.

According to the embodiment represented in FIG. 14, the distance “I”between the light guide 109 and the lenses 104 of the light modulesinside the spotlight 100 can be defined by a movement of the secondexterior part 115 of the spotlight 100 in relation to the first part 114of said spotlight 100. As indicated in FIG. 14, the first exterior part114 of the spotlight 100 is equipped with connection means forconnecting said spotlight 100 to the bracket 102.

FIG. 15 represents an embodiment of a spotlight 301 comprising a setquantity of light sources positioned so as to form a line. According tothe example in FIG. 15, light sources (not shown), such aslight-emitting diodes (LEDs), are positioned on a printed circuit 307.

A collimator 310 is positioned on each light-emitting diode (LED), inorder to guide the light generated with the LED in the direction of thefront face of the spotlight 301. There are lenses 304 present on thefront face of the spotlight 301. The assembly composed of the lightsource, the collimator 310 and the lenses 304 can generate a light beam320.

According to the embodiment represented in FIG. 15, the distance “I”between the external wall of the spotlight 301 and the assembly composedof said printed circuit 307 and said collimator 310 is adjustable. Thismeans that the distance “I” between the collimator 310 and the lenses304 can be adjusted with adjustment means so as to obtain a “zoom”effect. Thus, the shape of the beams 320 can be determined as a functionof the distance “I” between the collimators 310 and the lenses 304.

To enable the movement of the assembly composed of the printed circuit307 and the collimator 310 inside the spotlight 301, said assembly isfixed on adjustment means comprising two rails 315, 316. The adjustmentmeans of the spotlight 301 also comprise motors 318 enabling movement ofthe assembly composed of the printed circuit 307 and the collimator 310in relation to said rails 315, 316. Thus, the adjustment means comprisethe rails 315, 316 and the motors 318. Connection means 330 are providedon the exterior wall of the spotlight 301 to enable said spotlight 301to be connected, for example, to a bracket of a light device.

According to the embodiment represented in FIG. 15, five light sourcesand five collimators 310 are positioned on the printed circuit 307. Itshould be noted that any other quantity of light sources can be used toobtain a spotlight 301 of a certain size.

The embodiment represented in FIG. 16, shows an example of use of asingle light source cooperating with a single collimator 310. A singlelight source, such as a light-emitting diode (LED) is present on aprinted circuit 307. A collimator 310 is positioned on thelight-emitting diode (LED) so as to guide the light produced by saidlight-emitting diode (LED) in the direction of a lens 304. The assemblycomposed of the printed circuit 307 and of the collimator 310 is mobile.Thus, the distance between the lens 304 and the assembly composed of theprinted circuit 307 and of the collimator 310 is adjustable in relationto said lens 304 thanks to adjustment means comprising a first and asecond motor 318. The assembly as represented in FIG. 16 can be usedwithin a spotlight 301 equipped with a single light source.

FIG. 17 represents a schematic view of the inside of a spotlight 200according to a second embodiment. FIG. 17 also shows a printed circuit207 on which twenty-five light guides 209 are positioned. Each lightguide 209 is adapted for cooperating with a lens (not shown in FIG. 17)present on the front face of the spotlight 200. Each light guide 209comprises an optical axis 261. The optical axis 261, for one of thelight guides 209, is represented in FIG. 17. In an initial position, theassembly composed of the printed circuit 207 and the light guides 209 ispositioned so that each light guide 209 and each respective lens 204 arecentred around each optical axis 261.

According to the embodiment represented in FIG. 17, the assemblycomposed of the printed circuit 207 and the light guides 209 can bemoved in a first direction 270 essentially perpendicular in relation tothat of the optical axes 261 of the various light modules of thespotlight 200 and in a second direction 280, perpendicular to the firstdirection 270 and to that of the optical axes 261 of the light modulesof said spotlight 200.

To enable the movement in each of the directions above 270, 280, anadjustment means assembly composed of a first motor 218 and a belt 219is used respectively for movement in directions 270 and 280. FIG. 17shows adjustment means comprising three motors 218 and three belts 219.Another adjustment means composed of a motor 218 and a belt 219 can befound behind the printed circuit 207 and, hence, is not visible in FIG.17.

The light guides 209 can be moved in relation to the lenses (not shownin FIG. 17) in three directions, thanks to adjustment means asrepresented in FIG. 13. The first direction is a direction parallel tothat of the optical axes 261, the other two directions 270 and 280 beingperpendicular to each other. The technical effect of the optionconsisting in moving the assembly composed of the printed circuit 207and the light guides 209 in relation to the lenses 204 is represented indetail with reference to FIGS. 18a, 18b, 18c and 19.

Thus, FIGS. 18a, 18b and 18c shows the lens 204, in three differentpositions in relation to the optical axis 261, as well as the movementof the light source 208 in direction 270 with the aid of the adjustmentmeans as represented in FIG. 17. By moving the light source 208 inrelation to the centre of the lens 204, the exit direction of the lightbeam 20 obtained with the assembly composed of the light source 208, thelight guide 209 and the lens 204, can be modified.

FIG. 18a represents a mode of use where the centre of the lens 204 issituated on the optical axis 261. This means that the light beam 20 thusobtained offers an exit direction in extension of said optical axis 261.By moving the light source 208, the exit direction of the light beam 20thus obtained can be modified.

FIG. 18b represents a mode of use wherein the light source 208 is movedinto a lower position lower than that shown in FIG. 18a . Thus, thecentre 0 of the lens 204 is situated below the optical axis 261. Thismovement makes it possible to obtain a light beam 20 which shifts fromthe optical axis 261 by a set angle and in a first direction. FIG. 18crepresents a mode of use wherein the light source 208 is moved into aposition higher than that shown in FIG. 18a . This movement makes itpossible to obtain a light beam 20 which shifts from the optical axis261 by a set angle and in a second direction.

FIGS. 18a, 18b and 18c show the movement of the light source 208 in a 2Dplane. With reference to FIG. 17, it should be noted that movement ofthe assembly composed of the light source 208 and the light guide 209 inrelation to the lens 204 can also be performed in two other directions.The effect of this movement in two directions is representedschematically in FIG. 19. As soon as the position of the assemblycomposed of the light source 208 and the light guide 209 in relation tothe lenses 204 changes in directions 270, 280, as shown in FIG. 19, thelight beam 20 shifts from the optical axis 261 according to a set angle.The technical effect makes it possible in particular to obtain a lightbeam 20 which can represent an “8” shaped figure as shown in FIG. 19.

It should be noted that FIG. 19 represents one example of multiplepossible modes of use.

Thus, advantageously, within the present invention, the adjustment meansmake it possible to modify or adjust the relative position of the lightsource and the optical element. This means that the position of thelight source can be modified in relation to the position of the opticalelement, and conversely, the position of the optical element can also bemodified in relation to the position of the light source.
